 Connections A and C are both entirely reliable: A uses file descriptors and C uses TCP. Connection B, however, uses UDP and is not reliable. The result is that the whole connection `client SSH -> server SSH` is unreliable, yet since SSH is designed to run over TCP it has no facilities for dealing with this. At the first lost, corrupted, etc. packet the SSH session will be terminated.
 
-We fix connection B using SCTP-over-UDP via [sctp-echo](/cgit/sctp-echo). For the reasons described there, we require the use of [usrsctp](https://github.com/Kurento/libusrsctp) rather than the kernel implementations of SCTP.

 The two files `ssh_holepunch_client.py` and `ssh_holepunch_server.py` implement the two sides of this. We use `ssh_holepunch_server.py` just as `udp_holepunch.py server`, except it will open a connection to the SSH server once holepunching has been established.
